This was taken around half a decade ago when I visited Norway. Beautiful city and people! The Tyholt Tower is a 124m tall communications tower (probably the tallest building in all of Norway) that houses a restaurant and an observation deck. It revolves and completes one full revolution in an hour so you can enjoy a good meal and capture in all of Trondheim!
Notice a small islet on the top right. That’s Munkholmen, an islet that has in the past served as a place of execution, a monastery, a fortress, a prison, and also a World War II anti-aircraft gun station!
Straight onto the bucket list. Beautiful shot, OP!
